amount to deposit

How much money would have to be deposited now at 4.5% interest compounded monthly to accumulate to $6500 in 4 years?

Could someone please show me how to work this one? Which formula is it that I use?

Approximately $785.84...

785.84*(1.045[sup]48[/sup]) ≈ 6500

Hi zetafunc;

Isn't that a lot of money earned off of 4.5% interest?

I think the problem is that you have her earning 4.5% per month. She is only earning 1 / 12 of that per month.

Re: amount to deposit

But isn't it being compounded monthly?

It is a lot of interest -- I would have expected that to be per year.

That means a little bit better than 4.5 % because you get a bit per month.

Re: amount to deposit

So it is actually 4.59% monthly?

Re: amount to deposit

It is 4.5% / 12 monthly. That gives you a higher effective interest than compounding yearly.
